Is it somehow acceptable to say "this food/dish/product is full of protein"? saying that I am aware that the right and formal choice will be "high in protein".

    Syntactically it's fine. You can nit-pick about the semantics, but as this usage chart for foods {which are} full of sugar shows, the construction is quite common. Commented Jan 19 at 19:51

  • I'm only giving you my opinion - I can see why you might think it's "sub-standard", but I have no problem with it. Others may have different opinions, and it's possible they think it's at least "informal", even if it's not outright "wrong". I don't actually agree, but I'm not gonna try to talk you out of your stated position that the right and formal choice will be "high in protein". Commented Jan 19 at 20:06

    Fine grammatically, but factually it's probably inaccurate because "full of" suggests 100% or near, whereas even a high-protein food like lean meat is maybe only 30% protein. That said, "full of" is often used casually and inaccurately. (You should explain in the Q why you think "full of" is wrong; saying that "high in" is right doesn't explain that.)

Yes, it's completely normal in everyday speech, even if it isn't the most technical sounding. It's common, for example, to say foods are "full of goodness", "packed with vitamins" or "loaded with sugar". Simply put, 'full of' is an all-purpose phrase for saying something contains a lot of a particular thing.

  • When I and my friends were particularly energetic as kids, the adults would say we were 'full of beans'. Commented Jan 19 at 21:01

    In my early teens, yogurt began to be promoted as a mass-market product, rather than something for bearded, sandal-wearing health-nut weirdos. One product was Ski yogurt - Ski, the full-of-fitness food! (sung in the TV ads). Commented Jan 19 at 21:14
